DICKENS, F HAGERSTOWN, MARYLAND, ASSIIGNOR '.EC)v DICKENSAUTO TRANSMIESSION I-IOIST COMPANY INC., OF HAGERSTOWN, MARYLAND HOISTApplication ined september 1e, 1931. serial No. 563,212.

rlhis invention relates to a hoist and has forits primary object toprovide, in a mannerl as hereinafter set forth, a device of this`character which is portable Vand which embodies a novel construction,and arrange ment of'parts, whereby same is adapted particularly for usein removing and replacing transmission units of automobiles in anexpeditious manner.

a Other objects of the invention are to provide a transmission hoistwhich will be simple inconstruction, strong, durable, eihcient andreliable in use and whichmay be manufactured at lowcost.

5 All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of thefollowingspeciication, taken in connection with the accompanyingdrawings, wherein like char- G acters ofreference designatecorresponding parts throughout the several views, and

wherein Figure- 1 is a view in vertical section through a hoistconstructed in accordance with the present invention.

Fig. 2 is a View in vertical cross section taken substantially on theline 2--2 of Fig. 1, looking in the direction indicated by the arrows. j0 Fig. 3 is a view in horizontal cross section taken substantially onthe line 3 8 of Fig. l, looking downwardly as indicated by the arrows.

F ig. 1 is a View in top plan showing the hoistin position for use.

Fig.v 5 is a vertical sectional view taken substantially on the line 5&5of Fig. 1.

Fig. k6 -is a vertical sectional view taken substantially on the line6-6 of Fig. 1.

Fig. 7 is a detail view in perspective of one of the transmissionsupporting bars.

Referring now to the drawings in detail, it ,will be -seen that thehoist constituting the present invention comprises atubular bar 1 whichextends slidably thru the horizontally disposed feet 2 and which has itsends provided with the caps 3. These feet 2 are equipped with thesupporting casters 4. The reference numeral 5 designates rods which ared isposedinl spaced parallelism with the tubumembers 10 which telescopeinto the lower members 9.

rThe members 9 and 10 are provided with series of openings 11 which areadapted to be brought into registry for the reception of the pins 12 forsecuring the upper members 10 in adjusted position. The pins 12 may besecured to the lower members 9 of the standards 8, through the medium ofa chain 13, and a ring 14.

One of the upper members 10 of the standards 8, is provided at its upperend, with a bearing 15 in which one end portion of a horizontallydisposed tubular shaft 16 is journalled.. The other upper member 10 hasrigidly mounted thereon an upstanding casing 17 which is secured 1nposition in anyV suitable manner, as by a pin 18. A shaft 19 isjournalled horizontally in the casing 17 and has an enlarged end portion20 projecting therefrom for engagement in the other end portion of thetubular shaft 16 for supporting same.

Suitable means, such as a pin 21, is employed .for connecting thetubular shaft 16 to the enlarged projecting end portion 20 of theshaft'19 for rotation with said shaft 19. The inner end of the enlargedportion 20 of the shaft 19 is provided with a collar 22 against whichthe adjacent end of the tubular shaft 16 abuts. Y Y

A worm gear 23 is fixed on the shaft 19 in the casing 17. Journalled inthe casing 17 above the shaft 19 and at right angles thereto, andprojecting from the said casing 17 is a shaft 24 having fixed thereon aworm gear 25. A hand crank 26 is mounted on the projecting end portionofthe shaft 24 for manually rotating said shaft. If desired, the handcrank 26 may be removable. A hoisting chain 27 has one end fixed to thetubular shaft 16 and is windable thereon.

If desirable or necessary, more than one hoisting chain 27 may beprovided. The end of the tubular shaft 16 which is supported in thebearing is provided with a cap 28.

Mountedjfor slidingradj ustment on the rods 5 are the anti-clinaltransmission supporting bars 29, the apex portions of which rest on thetubular bar 1. At their ends the bars 29 terminate in the upstandingeyes 30 which slidably encircle the rods 5. The bars 29 are slidablyadjustable toward and away yfrom each other to accommodate differentsides of transmission units. In Fig. 4 of the drawings, a transmissionunit is designated by the j reference numeral 31, the same being shownin broken lines. A portion of the frame of a vehicle is also shown inbroken lines in Fig. 4 ofthe drawings and designated by the referencenumeral 32. o

In use, the floor boards of the vehicle which are forward of the driversseat are removed. The feet 2, with the standards 8 and tubular shaft 16removed therefrom are then rolled under the vehicle into positionbeneath the j transmission. The standards S are then mounted in thesocket members 7 and the members 10 of said standards are adjustedvertically as desired. Then, the tubular shaft 16 is mounted in positionand extends transversely above the transmission. The

I hoisting chain 27 is then secured properly to the transmission afterwhich said transmission may be unbolted and lowered to the supportingbars 29. The worm gears 23 and 25 prevent rotation of the tubular shaft16 except when actuated by the hand crank 26. TWith thetransmission'resting on the bars 29, the tubular shaft 16 and standards8` are again removed in order that the lower portions of the hoist withthe transmission thereon may be rolled from beneath the vehicle. j

It is believed thatthe method of replacing the transmission will beapparent from the foregoing description.

It is believed that the many advantages of a hoist constructed inaccordance with the present invention will be readily understood, andalthough the preferred embodiment of the invention is as illustrated anddescribed,

j j it is to be understood that changes in the details of constructionand in the combination and arrangement of parts, may be made which willfall within the scope of the invention as claimed.

Having thus described my invention, what I claim as new is u 1. A hoistcomprising a bar, a pair of feet slidable on the bar for adjustmenttoward and awayy from each other, supporting casters on the feet,standards rising from the feet, a
